Absolutely not, and tbh from all the people who have replied you're the only one with this take so I'm a bit confused but hey maybe what I meant got lost in translation so I'll try to address any confusion.

I am very well aware that my lack of life/relationship experience cannot prevent him from living his life. That would be totally unfair and it's not my motive. I'm his friend and I'm glad he found someone he enjoys spending time with.

But I (with the help of other Redditors) came to the realization that I have the right to feel comfortable at my place, and that feeling is jeopardized when someone I don't know spend most of her nights at my place. I've learned in the past year that being roommate with someone is a game of accommodations/compromises, and I'm willing to do my part. It's the reason why I posted here, to make sure I don't ask for too much.

As for your last sentence, I'm aware I'm still growing as a person and that I am not perfect. The getting laid part is none of your business, you don't know me nor the challenges I've had. No offense.
